Tree pruning is a management tool in agroforestry systems for reducing shade, enhancing nutrient cycling or providing fodder. However, little information is available on the effect of pruning manageme...
Runoff from human-dominated watersheds has greatly altered nitrogen (N) and phosphorus (P) cycling in lakes. Nutrients from human sources are distinct from those from undisturbed ecosystems in several...
I show that the growth ofTrichodesmium, the primary diazotrophic phytoplankton in tropical and subtropical oceans, can be limited by Ni availability in both trace metal–defined culture media and natur...
The western Pacific warm pool (WPWP) is a region of low nutrient and chlorophyll concentrations in which new production is generally considered to be supported by upward fluxes of nitrate from the dee...
We present a unified conceptual framework describing the competition between diazotrophs and nonnitrogen-fixing marine plankton and their interaction with three essential nutrient elements: nitroge...
Runoff from human-dominated watersheds has greatly altered nitrogen (N) and phosphorus (P) cycling in lakes. Nutrients from human sources are distinct from those from undisturbed ecosystems in several...
Most legumes in natural conditions form a symbiosis with arbuscular mycorrhizal (AM) fungi. AM fungi in saline soils have been reported to improve salinity tolerance and growth in plants.
A plant growth-promoting rhizobacterium (Azospirillum brasilense strain Az) and a biocontrol fungus (Trichoderma harzianum strain T24) have been evaluated for their individual and combined productio...
Kanvinde and Sastry (Appl. and Environ. Microbiol. 56:2087-2092, 1990) had previously demonstrated that A. tumefaciens has all the physiological characters of a diazotroph. Genetic evidence indicates...
The influence of the Mekong River (South China Sea) on N2 fixation and phytoplankton distribution was investigated during the lowest- and highest-discharge seasons (April 2007 and September 2008, resp...
Latitudinal distribution of diazotrophs and their nitrogen (N2) fixation activity were investigated in the western North Pacific in winter (Nov to Dec 2004) and summer (May to Jun 2005) along meridion...
We explored multiyear linear trends in nutrient concentrations, nitrogen (N) : phosphorus (P) ratio, and phytoplankton biomass within the 37-yr, whole-ecosystem nutrient enrichment experiment in Lake ...
Narrowleaf vetch (Vicia angustifolia L.) (NLV) is a legume widely distributed in the Eurasian continent. Although commonly growing as a weed in cultivated areas, NLV could become a suitable species fo...
The surface ocean absorbs large quantities of the CO2 emitted to the atmosphere from human activities. As this CO2 dissolves in seawater, it reacts to form carbonic acid. While this phenomenon, called...
Effects of (NH4)2SO4 top-dressing at the flowering stage to soybeans were investigated in view of its nitrogen fixation and assimilation. Possibility of estimating nitrogen fixation by time course mea...
